Abstract. The purpose of the present paper is to give some results relate to a class of linear bounded operators, known as -power class(Q) operators acting on infinite complex separable Hilbert space . -power class(Q) operators is extension of class(Q) operators and class of -normal operators The class of -power class (Q) operators was defined by S. Panayappan and N. Sivamani in [1], where they have given some of their properties. Based, mainly, on [1], [3], [4], we contribute with some others properties of such operators.
